| Abstract: | The plasma atomic emission spectroscopy detection method was developed for the simultaneous determination of lead , zinc and copper three metal elements of egg products.After the sample prior to microwave digestion, handling liquid into the ICP measurement , the results showed that the linear range of the three kinds of metal elements in a wide correlation coefficient （r） of 0.999 or more, the detection limits were 0.8, 0.4 and 1.0 mg/kg, respectively.The method was reliable , simple operation , and small reagent consumption. |
